Interface MutationEvent

All Superinterfaces:

Event

All Known Subinterfaces:

MutationNameEvent

All Known Implementing Classes:

DOMMutationEvent, DOMMutationNameEvent

public interface MutationEvent

extends Event

The MutationEvent interface provides specific contextual information associated with Mutation events.

To create an instance of the MutationEvent interface, use the DocumentEvent.createEvent("MutationEvent") method call.

See also the Document Object Model (DOM) Level 3 Events Specification .

DOM Level 2

MODIFICATION

public static final short MODIFICATION

The Attr was modified in place.

Constant Field Values

ADDITION

public static final short ADDITION

The Attr was just added.

Constant Field Values

REMOVAL

public static final short REMOVAL

The Attr was just removed.

getRelatedNode

public Node getRelatedNode()

relatedNode is used to identify a secondary node related to a mutation event. For example, if a mutation event is dispatched to a node indicating that its parent has changed, the relatedNode is the changed parent. If an event is instead dispatched to a subtree indicating a node was changed within it, the relatedNode is the changed node. In the case of the DOMAttrModified event it indicates the Attr node which was modified, added, or removed.

getPrevValue

public String getPrevValue()

prevValue indicates the previous value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharacterDataModified events.

getNewValue

public String getNewValue()

newValue indicates the new value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharacterDataModified events.

getAttrName

public String getAttrName()

attrName indicates the name of the changed Attr node in a DOMAttrModified event.

getAttrChange

public short getAttrChange()

attrChange indicates the type of change which triggered the DOMAttrModified event. The values can be MODIFICATION , ADDITION, or REMOVAL.

initMutationEvent

public void initMutationEvent(String typeArg,
                              boolean canBubbleArg,
                              boolean cancelableArg,
                              Node relatedNodeArg,
                              String prevValueArg,
                              String newValueArg,
                              String attrNameArg,
                              short attrChangeArg)

The initMutationEvent method is used to initialize the value of a MutationEvent object and has the same behavior as Event.initEvent().

Parameters:

typeArg - Refer to the Event.initEvent() method for a description of this parameter.

canBubbleArg - Refer to the Event.initEvent() method for a description of this parameter.

cancelableArg - Refer to the Event.initEvent() method for a description of this parameter.

relatedNodeArg - Specifies MutationEvent.relatedNode .

prevValueArg - Specifies MutationEvent.prevValue. This value may be null.

newValueArg - Specifies MutationEvent.newValue. This value may be null.

attrNameArg - Specifies MutationEvent.attrname. This value may be null.

attrChangeArg - Specifies MutationEvent.attrChange. This value may be null.

initMutationEventNS

public void initMutationEventNS(String namespaceURI,
                                String typeArg,
                                boolean canBubbleArg,
                                boolean cancelableArg,
                                Node relatedNodeArg,
                                String prevValueArg,
                                String newValueArg,
                                String attrNameArg,
                                short attrChangeArg)

The initMutationEventNS method is used to initialize the value of a MutationEvent object and has the same behavior as Event.initEventNS().
